[Paddlewise] Alaska Air luggage (again)

Still trying to digest this pill - sorry if I'm still confused.  My poor
brains are already overwhelmed, may be somebody can make sense out of the
following.  See
http://www.alaskaair.com/www2/company/tariff/tariff_main_toc.asp
 --> Domestic (or Canadian) contract of carrige --> Section V (baggage).
Read  "Free baggage allowance" (Domestic contract of carriage):

"maximum of two pieces of checked baggage. Maximum outside linear dimensions
per piece for checked baggage is 62 in. Each ticketed passenger is allowed
only one carry-on bag plus one personal item, such as a purse, briefcase or
laptop computer. The carry-on bag can measure up to 10"H x 17"W x 24"L (25 x
43 x 61 cm).
[and now, this is interesting]
 Duffel bags (a canvas cylindrical shaped bag, folded and fastened at one
end), sea bags (a canvas cylindrical shaped bag, closed at one end by means of
draw ropes), and B-4 bags (a suitcase-type handbag of canvas with leather and
metal bindings and fittings and with expandable canvas compartments on the two
sides of the bag), whose maximum outside linear dimensions exceed 62 in., or
which weigh more than 70 lb., will be transported free in lieu of the first
and second checked pieces. Maximum weight allowed will be 50 lb. "

1) So, duffel bag or "sea bag" can exceed 70 lbs 62" despite this new
regulation? Good news for me; they want it - they'll get it :-).
2) It is not clear, whether it is 50 lb for 2 bags or for each (I hope - for
each, but may be I'm wrong)?.
2) For some reason the last sentence (50 lbs) is missing in Canadian contract
of carriage.  I don't think they are so generous and forgot to lower
cross-border baggage down to 50 lb (because table for excessive baggage has
extra charge for bags "up to 70 lb") - but may be I've got it wrong?  Btw,
overweight surcharge for cross-border flights is USD 50 per bag up to 70 lb,
and USD 75 up to 100 lb.
Alex.
